Highly Efficient Laser-Ablation Propulsion System At Supersonic Speeds

by on October 30, 2014
Conventional rockets and aircraft exploit a combination of conservation of momentum and Newton’s third law to generate thrust via the expulsion of propellant mass from a nozzle to escape Earth’s atmosphere or travel through the atmosphere or space.  However, the expense and difficulty of the technique has prompted engineers and scientists to devise alternative methods […]

World Losing 2,500 Hectares Of Irrigated Land Per Day To Salt Damage

by on October 29, 2014
A study by scientists at the UN University’s Institute for Water, located in Ontario, Canada, revealed that 17 million hectares of arable land has been lost to salinization in the period from 1995 to 2013.  The loss rate is computed at a staggering 2,500 hectares per day, or equivalently 4,600 American football fields.  Viewed another […]

Clinical Trial Shows Cocoa Diet Reverses Age-Related Memory And Cognitive Decline: 60 Year Old Cognition Reverted to 30-40 Year Old

by on October 27, 2014
A new study and clinical trial by scientists at Columbia University Medical Center has shown that in healthy human adults, a diet of cocoa that is rich in flavanols is able to reverse the effects of age-related memory decline.  Imaging reveals one region of the brain that is responsible for the improvement in cognition.  The […]

21 Year Study Of Danish Olympic Rower Shows Remarkable Two Decade Maintenance Of Peak Physical Performance

by on October 27, 2014
Aging is associated with physical decline.  Previous studies have pointed out in average people, the maximum heart rate, the amount of oxygen carried by each beat of the heart, and maximum blood oxygen saturation all drop over the course of years.  But what if the decline is not inevitable?  Scientists have now studied a case […]

Biofuels Advancement: Cress Plant Engineered To Yield 150-Fold More Energy-Dense Biodiesel Molecules

by on October 25, 2014
Biodiesels are fuels used in standard combustion engines and usually are generated from an esterification reaction combining an alcohol with vegetable oil and animal fat among other biolipids.  Vegetable oils in turn are extracted from plants, in particular their seeds, as the lipid content of leaves, stems and stalks are low in oil. Now scientists […]

Acoustic Metamaterial Superenhances Sound Detection Limits By More Than 10 Fold

by on October 24, 2014
Metamaterials are composite materials with exacting, repetitive subwavelength structural patterns that have properties not found in nature.  Thus far, they have been used to create novel optical materials with negative index of refraction, thus permitting “superlenses” that have enhanced optical resolution beyond conventional lenses, and “invisibility cloaks” that bend at least a narrow band of […]

Iridescence Camouflages A Lizard’s Head Against Overhead Predator But Increases Visibility To Co-Level Mates

by on October 23, 2014
The phenomenon of iridescence is caused by microscopic regularities on the surface that scatter light in an angle-dependent fashion.  Scientists from Valencia University have discovered that not only are the heads of the Iberian emerald lizard iridescent, but the lizard seems to exploit the angle dependence by being innocuous when viewed above as from the […]

Human Skin Contains An Odor Receptor That Responds To Sandalwood Smells By Enhanced Healing

by on October 23, 2014
The skin is an important major organ, the function of which includes acting as a protective covering against injury for underlying tissue, as well as a sensing, cooling, and water retention among others.  Now German researchers have discovered that there is an odor receptor expressed in at least keratinocytes, a major skin cell type, and that […]

Noncovalent, Self-Assembled, Robust, Porous Material That Adsorbs Greenhouse Gas

by on October 22, 2014
Researchers from the Department of Chemistry at the University of Houston have created noncovalent organic frameworks, a new type of porous material that overcomes some barriers in the development of porous material technologies.  The new wonder material is highly processable, self-assembled, possessing of a superstructure with large, 16 angstrom pores (Figure above).  The material has a […]

Dark Matter X-Ray Signature From Beyond The Standard Model Revealed By Space Observatory

by on October 21, 2014
Astronomers analyzing 12 years worth of X-ray data from the European Space Agency Multi Mirror Mission (XMM-Newton) have found excess detected emissions comparing between two locations around the Earth.  In one location, at the Sun-side, more emissions were detected versus in the other location, at the far side.  Ruling out known sources of X-rays such […]
